Bound + Unbound in DataGridView and unbound won't sort...

Hello,

Win Forms .NET 2.0, Visual Studio 2008

I have a DataGridView with two columns, one bound and the second unbound.
When I load up the datagrid I set the columns in the unbound columns based
on the bound column.

Now if I click the header over the bound columns, while it sorts correctly
the contents of the unbound column are cleared.

The other problem is that if I click the unbound column's header nothing
happens.

What am I missing?

Thanks!
